在考虑研发网络企业间同时存在合作关系与竞争关系的基础上,引入风险恢复因子,从节点企业风险负荷的定义、阈值的确定,失效后如何影响邻居节点企业三个方面构建了R&D网络的风险传播模型,并进行了仿真.结果表明:在竞合的R&D网络中,关系风险可以在很短的时间内快速完成传播,三类关系风险中,机会主义风险最易发生影响范围更广泛;竞争企业占R&D网络规模的比例越大,竞争程度越激烈,关系风险的传播速度越快和影响范围越大;关系风险传播过程中,合作程度与竞争程度对风险传播都具有重要的影响,且合作程度比竞争程度对风险传播的影响更大;研发网络存在最佳的风险恢复水平,使得风险不再发生相继传播.该研究成果对于R&D网络抗风险能力的提高具有重要意义.
Based on the consideration of the existence of the cooperative relationship and the competitive relationship between the enterprises in the R & D network at the same time, this paper introduces the risk recovery factor and constructs the risk of R & D network from three aspects: the definition of the enterprise risk load, the determination of the threshold and how to affect the neighboring node enterprises after the failure The results show that in R & D network, the risk of relationship can be quickly transmitted in a short period of time. Among the three types of relationship risk, opportunistic risk is most likely to have a wider range of influence. Competition The bigger the proportion of enterprises in the R & D network, the more intense the competition, the faster the spread of the relationship risk and the bigger the influence range. In the course of the relationship risk communication, the degree of cooperation and the degree of competition have an important influence on risk transmission and cooperation The degree of competition has a greater impact on risk transmission than the degree of competition. The optimal risk recovery level exists in R & D networks so that the risk no longer occurs one after another.The research results are of great significance for the improvement of anti-risk ability of R & D networks.
